The Response of Planetary Atmospheres to the Impact of Icy Comets III: Impact Driven Atmospheric Escape

Felix Sainsbury-Martinez, Greg Cooke, Catherine Walsh

In an Earth-analogue atmosphere, water vapour is a key carrier of hydrogen in the lower atmosphere with its transport above the tropopause controlling the atmospheric hydrogen esca…

The Response of Planetary Atmospheres to the Impact of Icy Comets II: exo-Earth Analogues

F. Sainsbury-Martinez, C. Walsh

The orbital regime of a terrestrial planet plays a significant role in shaping its atmospheric dynamics, climate, and hence potential habitability. The orbit is also likely to play…

The Response of Planetary Atmospheres to the Impact of Icy Comets I: Tidally-Locked exo-Earths

Felix Sainsbury-Martinez, Catherine Walsh, Greg Cooke

Impacts by rocky and icy bodies are thought to have played a key role in shaping the composition of solar system objects, including the Earth's habitability. Hence, it is likely th…

How Land-Mass Distribution Influences the Atmospheric Dynamics of Tidally Locked Terrestrial Exoplanets

F. Sainsbury-Martinez, C. Walsh, G. J. Cooke +1

Interpretation of the ongoing efforts to simulate the atmospheres of potentially-habitable terrestrial exoplanets requires that we understand the underlying dynamics and chemistry…

Lethal surface ozone concentrations are possible on habitable zone exoplanets

G. J. Cooke, D. R. Marsh, C. Walsh +1

Ozone () is important for the survival of life on Earth because it shields the surface from ionising ultraviolet (UV) radiation. However, the existence of $\textrm{O}…

The Impact of Cometary 'impacts' on the Chemistry, Climate, and Spectra of Hot Jupiter Atmospheres

Felix Sainsbury-Martinez, Catherine Walsh

Impacts from icy and rocky bodies have helped shape the composition of solar system objects, for example the Earth-Moon system, or the recent impact of comet Shoemaker-Levy 9 with…
